摘要：
We study the nucleon electromagnetic form factors in a quark-gluon core model framework, which can be viewed as an extension of the Isgur-Karl model of baryons. Using this picture we derive nucleon electromagnetic dipole form factors at low Q(2) and the deviation from the dipole form at high Q(2), that are consistent with the existing experimental data.
